Key Features & Benefits

Structural Strength & Stability

Forged as a single-piece structure (crown, tripping palms, and flukes integrated), forming a heavy-head design that boosts holding capacity by 30% compared to ordinary anchors. This ensures vessels remain securely positioned even in strong currents and high winds.

Crafted from high-strength cast steel (ZG 200 - 400), which offers excellent impact resistance and load-bearing capacity, suitable for the rigorous demands of marine moorings.

Corrosion Resistance & Durability

Dual surface treatment options: black tarred painting (cost-effective, anti-corrosion for general marine environments) and hot dip galvanized (enhanced protection against saltwater erosion, ideal for long-term offshore use). Both extend the anchor’s service life to 15 - 20 years with proper maintenance.

Versatility & Compatibility

Weight range spanning 40 kg to 46000 kg, covering applications from small fishing boats and yachts to large commercial vessels (e.g., 300 kg for coastal cargo ships, 46000 kg for VLCCs).

Complies with global marine standards, making it compatible with international fleets and offshore projects worldwide.

Certification & Compliance

Holding multiple authoritative certifications, including IACS, BV, ABS, CCS, it meets the safety requirements of major maritime organizations. This eliminates compliance risks for vessel operators and simplifies customs clearance for international shipping.

Applications & Compatible Equipment

Primary Application Scenarios

Fleet Moorings: Long-term anchoring for commercial ships, naval vessels, and offshore platforms during port calls or maintenance.

Vessel Positioning: Stable positioning for cargo loading/unloading, offshore construction, and emergency anchoring in adverse weather.

Offshore Operations: Anchoring for oil platforms, FSO (Floating Storage and Offloading) units, and FPSO (Floating Production Storage and Offloading) units in deep-sea oil and gas exploration projects.

Compatible Vessel Types

Large commercial ships: VLCC (Very Large Crude Carrier), LNGC (Liquefied Natural Gas Carrier), LPGC (Liquefied Petroleum Gas Carrier), container ships, and bulk carriers.

Medium-sized vessels: Coastal cargo liners, passenger ferries, and fishing trawlers.

Specialized marine equipment: Offshore supply vessels, dredgers, and tugboats.

Supporting Equipment Compatibility

Works seamlessly with marine anchor chains (Grade 2, Grade 3, and R3 grades), chain stoppers, windlasses, and anchor winches from major manufacturers.

Compatible with standard marine hardware, ensuring easy integration into existing vessel anchoring systems.


Manufacturing Process


Packing, Production & Services

Packaging Solutions

Anchor Packaging: Nude packing (cost-effective, reduces transportation weight) with anti-rust oil coating on metal surfaces to prevent corrosion during transit.

Chain Packaging: Bundled with steel wire rope (5 - 10 tons per bundle) and wrapped in waterproof plastic film for moisture protection.

Custom packaging available upon request (e.g., wooden crates for small anchors or high-value orders).

Production Process

Advanced manufacturing workflow: Raw material inspection → Forging → Heat treatment → Machining → Surface treatment → Quality testing → Packaging.

Key production equipment: CNC forging machines, ultrasonic flaw detectors, and corrosion resistance testing equipment to ensure consistent quality.

Customer Service Offerings

One-stop Service: From product consultation, custom design (for special vessel requirements), to logistics and after-sales support.

Technical Support: Professional engineers provide anchoring system design, installation guidance, and maintenance training.

After-Sales Warranty: 2-year warranty against manufacturing defects; lifetime technical consultation and spare parts supply.

Response Time: Customer inquiries and service requests addressed within 2 working days.


FAQ

Can I place a custom order for an anchor with non-standard weight or dimensions?

Yes. We support custom manufacturing based on your vessel’s specifications. Please provide detailed requirements (weight, dimensions, material, and certification needs), and our engineering team will develop a solution within 3 working days.

What is the shipping method for bulk orders?

For orders over 50 tons, we arrange ocean shipping (FCL/LCL) to major ports worldwide. For urgent small orders, air freight is available at an additional cost.

How does the black painted finish compare to hot dip galvanized in terms of corrosion resistance?

The black tarred painting offers basic corrosion protection for coastal and short-term use (service life 8 - 10 years), while hot dip galvanized provides superior resistance to saltwater and harsh environments (service life 15 - 20 years). We recommend hot dip galvanized for offshore or long-term anchoring needs.

Is the anchor suitable for rocky seabeds?

It performs best in sand, clay, and silt seabeds. For rocky seabeds, we recommend pairing it with a grapnel anchor or custom fluke design—contact our technical team for tailored solutions.
